Description

  The present invention relates to a hot metal desulfurization apparatus and a moving cart fixing method thereof.

Conventionally, desulfurization treatment for removing sulfur content has been performed on hot metal obtained in a blast furnace.
In the desulfurization treatment, for example, the hot metal is taken out into the hot metal ladle, a desulfurizing agent is added to the hot metal ladle, and the mixture is stirred with a stirrer. (See Patent Document 1).
In the hot metal desulfurization apparatus of Patent Document 1, a hot metal ladle mounted on a carriage and movable, and a fixed stirring apparatus into which the carriage and the hot metal ladle can be introduced are used.
The stirring device is supported above the hot metal ladle by a gantry, and the stirrer can be introduced into the hot metal pan by moving up and down. A plurality of hot metal ladles and carts are installed and alternately introduced into the stirring device, and the other hot metal ladle is brought close to the exhausting device to remove residue.

In patent document 1 mentioned above, the hot metal ladle and the cart were moved. These hot metal ladles and carts are extremely heavy when the weight of the hot metal to be accommodated is also increased, so that the drive device becomes larger and the moving path needs to be reinforced.
On the other hand, a hot metal desulfurization apparatus has been developed in which a pair of hot metal ladles are fixed (can be tilted), and a stirring device is reciprocated between the hot metal ladles by a carriage (see Patent Document 2).
In the hot metal desulfurization apparatus of Patent Document 2, the moving stirrer is lighter than the hot metal ladle, the moving mechanism and the moving path may be simple, and the equipment cost is also preferable.

In the hot metal desulfurization apparatus described above, resonance due to stirring is a problem. That is, when a large amount of hot metal is driven by a stirrer, horizontal vibration about a vertical rotation axis is generated. This vibration increases near the natural frequency of the device and can affect the device.
In particular, in the hot metal desulfurization apparatus of Patent Document 2 described above, the stirring device can be moved in the horizontal direction by the carriage, and the carriage needs mechanical play for movement. It is likely to occur.
On the other hand, in patent document 2, in order to suppress the vibration at the time of stirring, the several fixing device is installed in the both sides of the trolley | bogie, and the trolley | bogie is being fixed with respect to the movement path | route.
However, the fixing device used in Patent Document 2 is, for example, a stopper that regulates the position in the horizontal direction by engaging the projections and depressions in the vertical direction, and slight play remains even in the fitted state. For this reason, a sufficient deterrent effect against vibration during stirring has not been obtained.

  The objective of this invention is providing the hot metal desulfurization apparatus which can fix the moving trolley of a stirring apparatus reliably, and its moving trolley fixing method.

  The hot metal desulfurization apparatus of the present invention is installed between a moving path connecting a plurality of hot metal ladle apparatuses, a moving carriage that supports the stirring apparatus and is movable along the moving path, and the moving carriage and the moving path. A plurality of stopper mechanisms, wherein the stopper mechanism is a fixed side member fixed to the moving path, a moving side member installed on the moving carriage, and the moving side member is fixed to the fixed side member. And at least one pair of the plurality of stopper mechanisms is arranged such that the horizontal components in the contact direction of each of the movable side members with respect to the fixed side member are opposite to each other. It is characterized by being.

In the present invention, the hot metal ladle can be stirred in a state in which the stirring device is moved along the moving path by the moving carriage and is arranged with respect to any of the hot metal ladle devices.
When agitation is performed, the moving member is brought into contact with the fixed member by the contact mechanism of the stopper mechanism, and the moving carriage is fixed to the moving path.
In at least one pair of the plurality of stopper mechanisms, the horizontal components in the contact direction of the movable member with respect to the fixed member are opposite to each other.
For this reason, even if there is play remaining between each of the pair of stopper mechanisms when the moving side member of one stopper mechanism is brought into contact with the fixed side member, the moving side member of the other stopper mechanism The remaining play can be eliminated by contacting the fixed member with the fixed member.
Therefore, according to this invention, the play between a moving trolley and a movement path | route can be eliminated, the moving trolley | bogie of a stirring apparatus can be fixed reliably, and the vibration at the time of stirring can be suppressed reliably.

In the present invention, rails laid on the base can be used as the movement route. As a trolley | bogie, what has the wheel which rolls on a rail can be utilized.
As the fixed side member of the stopper mechanism, a member that can contact the moving side member, such as a plate material, can be used. The fixed side member may be fixed directly to the base of the moving path or the like, or may be fixed via a bracket or the like.
The moving side member of the stopper mechanism is desirably a member that can come into contact with the fixed side member, for example, a shape that can come into contact even if the contact direction slightly deviates, such as a cylindrical shape or a spherical shape. The moving side member may be fixed directly to the frame of the moving carriage, or may be fixed via a bracket or the like.
The moving side member and the fixed side member are brought into contact with each other in a state including a horizontal component in order to suppress vibration during stirring.

As a contact mechanism of the stopper mechanism, one of the moving side member and the fixed side member is moved along the contact direction from a state of being opposed to each other, so that the moving side member directly contacts the fixed side member. A contact configuration is available. Further, by using a press-fitting member different from the moving side member or the fixed side member, driving the press-fitting member in a direction crossing the contact direction, and press-fitting the gap between the moving side member and the fixed side member, It is good also as a structure which makes a movement side member contact | abut indirectly with respect to a fixed side member.
As a moving mechanism for the moving side member or the fixed side member, or a driving mechanism for moving the press-fitting member, for example, a hydraulic cylinder or the like can be used, and a mechanism that reciprocates by a motor and a gear mechanism can be used.

In the hot metal desulfurization apparatus of the present invention, it is preferable that the pair of stopper mechanisms arranged in the opposite directions are arranged such that the fixed side members face each other.
In the present invention, the movable carriage and the pair of moving side members installed on the movable carriage are disposed between the fixed side members of the pair of stopper mechanisms. As a result, the movable carriage is in a state where the two movable members are sandwiched between the pair of stationary members, and can be reliably fixed.

In the hot metal desulfurization apparatus of the present invention, in the pair of stopper mechanisms arranged in the opposite directions, it is preferable that the fixed side members are arranged back to back.
In the present invention, the fixed side members of the pair of stopper mechanisms can be sandwiched by the pair of moving side members installed on the movable carriage, and can be fixed securely.

In the hot metal desulfurization apparatus of the present invention, it is preferable that at least two pairs of the stopper mechanisms disposed in the opposite directions are installed in the crossing direction.
In the present invention, two sets of a pair of stopper mechanisms are installed in the crossing direction, thereby determining the position in the horizontal plane of the moving carriage with respect to the moving path, and generating horizontal vibration around the vertical rotation axis of the stirring device. Can all be suppressed.

  In the present invention, as two sets of the pair of stopper mechanisms installed in the crossing direction, one of the pair of stopper mechanisms can be the moving direction of the moving carriage and the other can be the width direction of the moving carriage. Moreover, you may arrange | position two sets of a pair of stopper mechanisms diagonally with respect to the moving direction of a mobile trolley, respectively. For example, if the planar shape of the movable carriage is rectangular, two sets can be arranged in each diagonal direction.

In the hot metal desulfurization apparatus of the present invention, it is preferable that at least one of the fixed side member and the movable side member that are in contact with each other is supported so as to be swingable.
In the present invention, when the moving side member abuts on the fixed side member, even if one of them is tilted with respect to the intended contact direction, the moving side member or the fixed side member swings appropriately. Can be obtained.
As a configuration for swinging the moving side member or the fixed side member, a pivotal support structure such as a pin joint or a ball joint, a swinging structure by fitting a groove such as a V groove, or the like can be used as appropriate.

In the hot metal desulfurization apparatus of the present invention, it is preferable that the contact mechanism is installed on the moving carriage together with the moving side member.
In the present invention, the contact mechanism and the moving side members are installed as many as necessary for the moving carriage. On the other hand, a fixed number of fixed-side members are installed for each position where the mobile carriage should stop. When the abutment mechanism is installed on the moving path side together with the fixed side member, it is necessary to install a predetermined number of the abutment mechanisms for each stop position. The number can be reduced, and the structure can be simplified.

  In the hot metal desulfurization apparatus of the present invention, the abutment mechanism includes a press-fit member that can be press-fitted between the fixed side member and the movable side member, and the press fit member that is installed in the movable carriage and moves the movable carriage. A drive mechanism that drives in a press-fitting direction that intersects the direction, the moving side member has a surface that is parallel to the press-fitting direction and intersects the moving direction of the moving carriage, and the fixed side member has a surface It is preferable to have a surface that is inclined with respect to the press-fitting direction and intersects the moving direction of the movable carriage.

In the present invention, in the contact mechanism, the press-fitting member is moved by the drive mechanism, so that the press-fitting member is press-fitted between the inclined surface of the fixed side member and the moving side member, and the moving side member is interposed via the press-fitting member. It abuts on the stationary member.
In other words, the moving side member and the fixed side member can be brought into contact with each other only by moving the press-fitting member with the drive mechanism. Therefore, the fixed side member and the moving side member may be fixedly installed, and the strength is ensured. However, the structure can be simplified.

In the hot metal desulfurization apparatus of the present invention, the contact mechanism may be installed not on the moving carriage side but on the moving path side.
In such a case, the contact mechanism is a press-fit member that can be press-fitted between the fixed-side member and the movable-side member, and is installed in the movement path to drive the press-fit member in a press-fitting direction that intersects the moving direction of the movable carriage. The fixed-side member has a surface parallel to the press-fitting direction and intersecting the moving direction of the moving carriage, and the moving-side member is inclined with respect to the press-fitting direction and the moving direction of the moving carriage A structure having a surface intersecting with the surface may be used.

In the hot metal desulfurization apparatus of the present invention, the drive mechanism has the movement limit of the press-fitting member set sufficiently longer than a position where the press-fitting member is press-fitted between the moving side member and the fixed side member. It is preferable.
In the present invention, a sufficient margin is obtained for the stroke of the drive mechanism, so that the press-fitting member can be reliably press-fitted between the stationary member and the moving member. In other words, if the drive mechanism reaches the movement limit before the press-fitting member is press-fitted between the fixed-side member and the movable-side member, there is a possibility that the press-fitting member cannot be fully pressed. By setting the limit sufficiently long, reliable press-fitting can be performed.

In the hot metal desulfurization apparatus of the present invention, it is preferable that the press-fitting member has a cylindrical shape or a cylindrical shape having a flat portion at a part of the peripheral surface.
In the present invention, since the press-fitting member has a cylindrical shape, reliable contact can be obtained even if the contact direction is shifted in the circumferential direction. On the other hand, unnecessary rotation of the press-fitting member can be prevented by using a cylindrical shape having a flat portion on a part of the peripheral surface and causing the flat portion to be along the surface of the moving side member or the fixed side member.

  A moving carriage fixing method for a hot metal desulfurization apparatus according to the present invention includes a moving path connecting a plurality of hot metal ladle apparatuses, a moving carriage that supports a stirring device and is movable along the moving path, the moving carriage, and the moving path. A plurality of stopper mechanisms installed between the fixed-side member fixed to the moving path, the moving-side member installed on the moving carriage, and the moving-side member. An abutment mechanism for abutting the fixed side member with each other, and at least one of the plurality of the stopper mechanisms has a horizontal component in a contact direction of the movable side member with respect to the fixed side member opposite to each other. A moving carriage fixing method for a hot metal desulfurization apparatus arranged in an orientation, wherein the moving carriage is moved to a position corresponding to the hot metal ladle apparatus on the movement path, and first of the pair of stopper mechanisms, Stock A positioning operation is performed in which the moving-side member of the mechanism is brought into contact with the fixed-side member of the one stopper mechanism, and then the moving-side member of the other stopper mechanism of the pair of stopper mechanisms is moved. A fixing operation of abutting against the fixed side member of the one stopper mechanism is performed.

In the present invention, the hot metal ladle can be stirred in a state in which the stirring device is moved along the moving path by the moving carriage and is arranged with respect to any of the hot metal ladle devices.
When agitation is performed, the moving side member can be brought into contact with the fixed side member by the contact mechanism of the stopper mechanism, and the moving carriage can be fixed to the moving path.
In particular, the movable carriage can be positioned with respect to the movement path by bringing the movable member of one of the stopper mechanisms into contact with the stationary member. Even if play remains between the moving side member and the fixed side member during the positioning operation, the remaining play is caused by the fixing operation of bringing the moving side member of the other stopper mechanism into contact with the fixed side member. In this state, the movable carriage can be fixed to the movement route.
Therefore, according to this invention, the play between a moving trolley and a movement path | route can be eliminated, the moving trolley | bogie of a stirring apparatus can be fixed reliably, and the vibration at the time of stirring can be suppressed reliably.

  In the moving carriage fixing method of the hot metal desulfurization apparatus of the present invention, two pairs of the stopper mechanisms are installed along the moving direction of the moving carriage between the moving carriage and the movement path. It is preferable that the positioning operation is performed simultaneously by two sets of the stopper mechanisms, and then the fixing operation is performed simultaneously by two sets of the pair of stopper mechanisms.

  In the present invention, by arranging two sets of the pair of stopper mechanisms on both sides of the moving carriage, for example, the moving carriage moving on the movement path has an inclination (rotation around the vertical direction) with respect to the movement path. Even in such a case, the moving carriage can be positioned in a correct posture with respect to the moving path by the two sets of positioning operations. Then, by the subsequent fixing operation, the movable carriage can be fixed with respect to the movement path in a correct posture.

[First Embodiment]
1 to 13 show a first embodiment of the present invention.
In FIG. 1 and FIG. 2, the hot metal desulfurization apparatus 1 of this embodiment performs stirring with respect to two hot metal ladle apparatuses 10 by using one stirring apparatus 20.

The hot metal ladle apparatus 10 has a hot metal ladle 11 for storing hot metal, and the hot metal ladle 11 is placed on a hot metal ladle cart 12. The hot metal ladle cart 12 is supported so as to be movable along a rail 14 laid on a foundation 13.
The hot metal ladle device 10 moves the hot metal ladle carriage 12 along the rail 14 so that the hot metal ladle 11 moves between the stirring position PS (upper side in FIG. 2) and the supply / discharge position PF (lower side in FIG. 2). You can make a round trip.

When in the stirring position PS, the hot metal stored in the hot metal ladle apparatus 10 is stirred by the stirring apparatus 20 described later.
When in the supply / discharge position PF, the hot metal ladle 11 loaded with hot metal is supplied to the hot metal ladle apparatus 10, or the hot metal ladle 11 loaded with hot metal is taken out from the hot metal ladle apparatus 10. In the vicinity of the supply / discharge position PF, an unillustrated evacuation device is installed in order to remove residues remaining on the upper surface of the hot metal.
Two hot metal ladle apparatuses 10 (hot metal ladle apparatus 10A and hot metal ladle apparatus 10B) are installed in parallel in their reciprocating directions.

  The stirrer 20 includes a stirrer 21 that can be introduced into the hot metal ladle 11, and includes a drive device 22 that rotates the stirrer 21 and a lift device 23 that drives the stirrer 21 and the drive device 22 up and down. The stirrer 21 or the lifting device 23 is supported by the movable carriage 24.

The movable carriage 24 can move along the rail 26 by rolling with the wheels 25.
The rail 26 is supported by struts 27 installed on the foundation 13 so as to straddle the hot metal ladle apparatus 10A and the hot metal ladle apparatus 10B (see FIG. 2), and the direction in which the hot metal ladle apparatus 10 reciprocates (continuous direction of the rail 14). ) (See FIG. 1).
The rail 26 and the support column 27 described above constitute a moving path 28 through which the moving carriage 24 can move.

The movement path 28 linearly connects the stirring positions PA and PB of the plurality of hot metal ladle apparatuses 10 and the maintenance position PC.
The stirring position PA is directly above the stirring position PS of the hot metal ladle apparatus 10A, and the stirring apparatus 20 can introduce the stirrer 21 into the hot metal pan 11 of the hot metal ladle apparatus 10A and stir it at the stirring position PA. .
The stirring position PB is directly above the stirring position PS of the hot metal ladle apparatus 10B, and the stirring apparatus 20 can introduce the stirrer 21 into the hot metal pot 11 of the hot metal ladle apparatus 10B and stir it at the stirring position PB. .
The maintenance position PC is on an extension of a straight line connecting the stirring positions PA and PB, and the lower portion of the rail 26 is an empty space. By placing the stirring device 20 at the maintenance position PC, the maintenance check of the stirrer 21 is performed. It can be carried out.

3 to 6 show details of the moving carriage 24. FIG.
3 and 4, the movable carriage 24 has a flat rectangular frame 240 made of steel, and includes a stage 241 on which the stirring device 20 (see FIGS. 1 and 2) is placed. Yes. The wheels 25 described above are supported at four corners of the frame 240 via a carriage frame 242.

On the side surface of the frame 240, six stopper mechanisms 40 are installed on each side, three on each side. Among these, the stopper mechanism 40A disposed on the left side in FIGS. 3 and 4, the stopper mechanism 40B disposed on the right side, and the stopper mechanism 40C disposed in the middle of these have the same configuration. Each direction is different from each other.
5, in the stopper mechanism 40A and the stopper mechanism 40B, a moving side member 41 or a fixed side member 44, which will be described later, are arranged along the moving direction of the moving carriage 24 (R direction in FIG. 3).
In FIG. 6, the stopper mechanism 40 </ b> C has a movable side member 41 or a fixed side member 44, which will be described later, arranged along the width direction of the movable carriage 24 (W direction in FIG. 3).

FIG. 7 shows the stopper mechanism 40 of the present embodiment.
The stopper mechanism 40 includes a moving side member 41 and a driving cylinder 42 installed on the moving carriage 24, a press-fitting member 43 supported by the driving cylinder 42, and a fixed side member 44 fixed to the moving path 28.

The moving side member 41 is a flat steel material, and is fixed to the frame 240 of the moving carriage 24 via a bracket 411.
In the stopper mechanism 40 </ b> C, the surface of the moving side member 41 is arranged along the vertical direction and in a direction intersecting with the moving direction of the moving carriage 24. Further, the stopper mechanisms 40A and 40B are arranged along the vertical direction and along the continuous direction of the rail 26 in the movement path 28 (that is, the movement direction of the movable carriage 24). The difference in the arrangement of the stopper mechanisms 40A, 40B and the stopper mechanism 40C can be arbitrarily set by changing the orientation of the bracket 411 with respect to the frame 240.

The drive cylinder 42 is composed of a reciprocating drive mechanism such as a hydraulic cylinder, and is fixed to the frame 240 of the movable carriage 24 in a state where the advance / retreat direction is the vertical direction.
The press-fitting member 43 is a cylindrical steel material, is supported by the drive cylinder 42, and can be moved up and down by its advance and retreat. The peripheral surface of the press-fitting member 43 is in contact with the surface of the moving side member 41 or is disposed so as to face the surface at a slight interval.
In the drive cylinder 42, the movement limit of the press-fitting member 43 is sufficiently (downward) than a position (shown by a solid line in FIG. 7) where a press-fitting member 43 described later is press-fitted between the moving side member 41 and the fixed side member 44. Accordingly, the press-fitting member 43 can be press-fitted between the moving side member 41 and the fixed side member 44 with a sufficiently strong force.

The fixed side member 44 is a block-shaped steel material supported by the bracket 262 of the movement path 28. The bracket 262 is fixed to the support structure of the rail 26 or the like.
The stationary member 44 is provided with a contact plate 441 formed of a flat steel material.
The abutting plate 441 is opposed to the above-described moving-side member 41 and is inclined upward. When the press-fitting member 43 is lowered by the drive cylinder 42, it comes into contact with the contact plate 441, and further descends into a V-shaped gap formed by the moving side member 41 and the contact plate 441. Press fit. As a result, the moving side member 41 and the fixed side member 44 are indirectly in contact with each other via the press-fitting member 43 (shown by a solid line in FIG. 7).

  The upper end position of the fixed side member 44 is disposed sufficiently below the lower end position of the moving side member 41. Therefore, in a state where the press-fitting member 43 is pulled up (shown by a chain line in FIG. 7), when the movable carriage 24 moves along the movement path 28, the upper end of the fixed side member 44 and the lower end of the movement side member 41 interfere with each other. Never do.

  The fixed side member 44 has a rotation mechanism 442 that can rotate about a vertical rotation axis at a portion supported by the bracket 262. If the surface of the moving member 41 and the horizontal component of the surface of the contact plate 441 of the fixed member 44 are not parallel, one-side contact may occur between the peripheral surface of the press-fitting member 43 that is press-fitted in the middle. There is sex. However, in such a case, the stationary member 44 is rotated by the rotating mechanism 442 so that the contact plate 441 is swung following the surface of the movable member 41 and the peripheral surface of the press-fitting member 43. It is possible to automatically eliminate the contact.

  As shown in FIG. 7, the fixed-side member 44 is not limited to the member in which the contact plate 441 is swung by the rotation mechanism 442, and as illustrated in FIG. The contact plate 441 is swingably supported on the fixed-side member 44 via a swingable groove fitting structure 443 such as a combination with a protrusion or a fitting between a V groove and a V-shaped protrusion. It is good also as a structure.

  In the stopper mechanism 40 of the present embodiment, the drive cylinder 42 is the drive mechanism of the present invention, and the drive cylinder 42, the press-fitting member 43, the moving side member 41 and the fixed side member 44 arranged in a V shape, The contact mechanism of the invention is configured.

In the present embodiment, the press-fitting member 43 has a cylindrical shape as shown in FIG. 7, but the following modifications are possible as the press-fitting member.
As shown in FIG. 8, a press-fitting member 43A having a flat portion 431 in a part of a cylindrical shape may be used. In this case, unnecessary rotation of the press-fitting member 43A can be prevented by causing the flat portion 431 to be along the surface of the moving member 41.
As shown in FIG. 9, a block 43 </ b> B having a cylindrical surface may be supported at the tip of the drive cylinder 42, and the cylindrical surface may be brought into contact with the contact plate 441.
As shown in FIG. 10, a block 43 </ b> C having an inclined surface may be supported at the tip of the drive cylinder 42, and the inclined surface may be brought into contact with the contact plate 441.

  Further, in the present embodiment, in the fixed side member 44, the contact plate 441 can swing with respect to the movement path 28, but in the movement side member 41, the contact surface swings with respect to the moving carriage 24. It is good also as a possible structure, and the contact state with respect to the fixed side member 44 of the movement side member 41 can be stabilized also in such a structure.

Returning to FIG. 3, in the movable carriage 24 of the present embodiment, the above-described stopper mechanism 40 is installed as the stopper mechanisms 40 </ b> A and 40 </ b> B and the stopper mechanism 40 </ b> C, respectively.
The position of the moving carriage 24 in the moving direction (R direction) is regulated by the pair of stopper mechanisms 40A and 40B on both sides of the moving carriage 24, and the width direction (W direction) of the moving carriage 24 is controlled by the pair of stopper mechanisms 40C. Position restriction is performed.

FIG. 11 schematically illustrates the position regulating operation of the movable carriage 24 by the pair of stopper mechanisms 40A and 40B on both sides and the pair of stopper mechanisms 40C.
As described above, the movable carriage 24 can move along the movement path 28 by traveling on the rail 26 with the wheels 25. Then, in the state where the stopper mechanisms 40A, 40B, and 40C are released, the position restriction on the movable carriage 24 is not performed.
On the other hand, when the stopper mechanisms 40A, 40B, and 40C are brought into contact with each other, the position of the movable carriage 24 is regulated by each.

In the two upper and lower stopper mechanisms 40 </ b> A installed on the left side in FIG. 11, the press-fitting member 43 is press-fitted between the moving-side member 41 and the fixed-side member 44. The member 44 is contacted leftward (R + direction) in the figure, and the movement of the movable carriage 24 in the R + direction is restricted.
In the two upper and lower stopper mechanisms 40 </ b> B installed on the right side in FIG. 11, the press-fitting member 43 is press-fitted between the moving-side member 41 and the fixed-side member 44. The member 44 is contacted rightward (R-direction) in the figure, and movement of the movable carriage 24 in the R-direction is restricted.
The position in the R direction with respect to the movement path 28 of the movable carriage 24 is regulated by the contact in the R + direction and the contact in the R− direction of the two sets of stopper mechanisms 40A and 40B.
And in the pair of stopper mechanisms 40C vertically installed in the middle of the moving carriage 24, the press-fitting member 43 is press-fitted between the moving-side member 41 and the fixed-side member 44, so that each side The member 41 and the fixed-side member 44 are in contact with each other upward (W + direction) in the figure and downward (W− direction) in the figure, and the position of the movable carriage 24 in the width direction (W direction) is restricted.

In the present embodiment, the position restriction of the movable carriage 24 by the stopper mechanisms 40A, 40B, and 40C is performed in the following procedure.
First, with the stopper mechanisms 40A, 40B, 40C being released, the movable carriage 24 is moved in the R-direction and stopped at a predetermined position. The stop position at this time is, for example, a position at an interval at which the movable member 41 and the fixed member 44 can press-fit the press-fitting member 43 between them in the stopper mechanism 40C on the right side of FIG.

  In this state, the press-fitting member 43 of the stopper mechanism 40B is lowered, and the movable member 41 and the fixed member 44 are brought into contact with each other via the press-fitting member 43 (see FIG. 12). At this time, the press-fitting of the press-fitting member 43 is set to a predetermined stroke position before the advance limit of the drive cylinder 42. Due to the press-fitting of the press-fitting member 43, the movable carriage 24 may slightly move in the R + direction.

Next, the press-fitting member 43 of the stopper mechanism 40A is lowered, and the movable member 41 and the fixed member 44 are brought into contact with each other through the press-fitting member 43 (see FIG. 13). By this press-fitting, the movable carriage 24 comes into contact with both the R + direction and the R− direction, and the position of the movable carriage 24 in the R direction with respect to the movement path 28 is regulated.
At this time, the press-fitting of the press-fitting member 43 is set to a predetermined stroke position before the limit of advancement of the drive cylinder 42, and the movable member 41 and the fixed member 44 are reliably applied to both the stopper mechanisms 40A and 40B. Be touched.
Subsequently, the press-fitting member 43 of the stopper mechanism 40C is lowered, and the moving side member 41 and the fixed side member 44 are brought into contact with each other through the press-fitting member 43 (see FIG. 11). Thereby, the position of the moving carriage 24 whose position in the R direction has already been restricted is also restricted in the W direction, and the position of the moving carriage 24 relative to the movement path 28 is restricted in all directions.

According to the first embodiment described above, the following effects can be obtained.
In this embodiment, the stirring apparatus 20 is moved along the movement path 28 by the moving carriage 24, and the hot metal ladle 11 is stirred in a state where it is arranged with respect to any of the plurality of hot metal ladle apparatuses 10A and 10B. be able to.
When agitation is performed, in each of the stopper mechanisms 40A, 40B, and 40C, the press-fitting member 43 is lowered by the drive cylinder 42 and press-fitted between the moving-side member 41 and the fixed-side member 44, thereby moving-side member. 41 and the stationary member 44 can be indirectly contacted to fix the movable carriage 24 to the movement path 28.

Of the plurality of stopper mechanisms 40A, 40B, 40C, two sets of stopper mechanisms 40A, 40B on both sides are paired with each other in the R direction along the moving path 28, and the contact direction of the moving side member 41 with respect to the fixed side member 44 Are in opposite directions (R + direction and R− direction). Further, in the stopper mechanism 40C, a pair is installed in the W direction that is the width direction of the moving path 28, and the horizontal components in the contact direction of the moving side member 41 with respect to the fixed side member 44 are opposite to each other (W + direction and W− Direction).
For this reason, when one moving side member 41 of the pair of stopper mechanisms 40A, 40B, and 40C is brought into contact with the fixed side member 44 via the press-fitting member 43, there remains play between them. Also, the remaining play can be eliminated by bringing the other moving side member 41 into contact with the fixed side member 44.
Therefore, according to this embodiment, the play between the moving trolley 24 and the moving path 28 can be eliminated, the moving trolley 24 of the stirring device 20 can be securely fixed, and vibration during stirring is reliably suppressed. be able to.

In the present embodiment, two pairs of stopper mechanisms 40A and 40B are arranged on both sides of the moving carriage 24 in the R direction opposite to each other, and the pair of stopper mechanisms 40C on both sides of the moving carriage 24 are opposite in the W direction. Has been placed.
In each of these pairs, the respective fixed side members 44 are arranged so as to face each other, and between each of these pairs of fixed side members 44, there is a movable carriage 24 and a pair of movable side members 41 installed thereon. Be placed.
As a result, the movable carriage 24 is in a state where the two moving side members 41 are sandwiched between the pair of fixed side members 44 by press-fitting the press-fitting members 43 into contact with each other. It can be fixed securely.

  In the present embodiment, the pair of stopper mechanisms 40A and 40B are disposed in the reverse direction in the R direction, and the pair of stopper mechanisms 40C are disposed in the reverse direction in the W direction. As described above, the pair of stopper mechanisms 40A and 40B and the pair of stopper mechanisms 40C, ie, two pairs (two directions) of the stopper mechanisms 40 are installed in the crossing direction, so that the horizontal surface of the movable carriage 24 with respect to the movement path 28 is obtained. The horizontal position can be determined, and all horizontal vibrations generated around the vertical rotation axis of the stirring device 20 can be suppressed.

  In the present embodiment, the fixed side member 44 including the contact plate 441 is rotatably supported on the movement path 28 via the rotation mechanism 442 (see FIG. 7), or the contact plate 441 is fixed to the fixed side member 44. And slidably supported by a groove fitting structure 443 (see FIG. 8). For this reason, when the moving side member 41 abuts on the fixed side member 44, the moving side member 41 or the fixed side member 44 swings even if one of them is inclined with respect to the intended contact direction. Thus, an appropriate contact state can be obtained.

  In the present embodiment, the drive cylinder 42 and the press-fitting member 43 serving as a contact mechanism for bringing the moving side member 41 into contact with the fixed side member 44 are installed in the moving carriage 24. That is, the fixed side member 44 needs to be installed at a position where the moving carriage 24 of the moving path 28 should stop, but the moving side member 41, the drive cylinder 42, and the press-fitting member 43 are the minimum in the moving carriage 24. It is only necessary to install a number. Therefore, about the drive cylinder 42 and the press-fit member 43, the number of installation as the whole hot metal desulfurization apparatus 1 can be reduced, and a structure can be simplified.

  In this embodiment, as a contact mechanism of the stopper mechanism 40 (40A, 40B, 40C), a press-fitting member 43 that can be press-fitted between the fixed-side member 44 and the movable-side member 41, and a press-fitted by being installed in the movable carriage 24. Using the drive cylinder 42 that drives the member 43 in the press-fitting direction (vertically downward) intersecting the moving direction (R direction) of the moving carriage 24, the moving-side member 41 is parallel to the press-fitting direction and the moving direction of the moving carriage 24 The fixed-side member 44 has a contact plate 441 that forms a surface whose surface is inclined with respect to the press-fitting direction and intersects the moving direction of the movable carriage 24.

For this reason, in this embodiment, the press-fitting member 43 is moved by the drive cylinder 42 so that the press-fitting member 43 faces the inclined contact plate 441 of the stationary member 44 and the contact plate 441 of the movable member 41. The movable side member 41 is brought into contact with the fixed side member 44 via the press-fit member 43.
That is, the moving side member 41 and the fixed side member 44 can be brought into contact with each other only by moving the press-fitting member 43 with the drive cylinder 42. The fixed side member 44 and the moving side member 41 are moved along the moving path 28 and the moving side, respectively. What is necessary is just to install fixedly to the trolley | bogie 24, and a structure can be simplified, ensuring intensity | strength.

In the present embodiment, the drive cylinder 42 has the movement limit of the press-fitting member 43 sufficiently longer than the position where the press-fitting member 43 is press-fitted between the moving side member 41 and the fixed side member 44.
As a result, a sufficient margin is obtained for the stroke of the drive cylinder 42, so that the press-fitting member 43 can be reliably press-fitted between the fixed-side member 44 and the moving-side member 41. That is, if the drive cylinder 42 reaches the movement limit before the press-fitting member 43 is press-fitted between the fixed side member 44 and the moving side member 41, there is a possibility that the press-fitting member 43 cannot be fully press-fitted. In addition, when the movement limit of the drive cylinder 42 is set to be sufficiently long, reliable press-fitting can be performed.

  In the present embodiment, the press-fitting member 43 has a cylindrical shape or a cylindrical shape having a flat portion on a part of the peripheral surface, so that reliable contact can be obtained even if the contact direction is shifted in the circumferential direction. On the other hand, an unnecessary rotation of the press-fitting member 43 can be prevented by using a cylindrical shape having a flat portion on a part of the peripheral surface and having the flat portion along the surface of the moving side member 41 or the fixed side member 44.

  In the present embodiment, as an operation for fixing the moving carriage 24 to the moving path 28, the moving carriage 24 is moved to a position corresponding to the hot metal ladle device 10 on the moving path 28, and first, a pair of stopper mechanisms 40A, 40B. Among them, in one stopper mechanism 40B, the press-fitting member 43 is moved down to bring the moving side member 41 into contact with the fixed side member 44 to perform the positioning operation. Next, in the other stopper mechanism 40A, the press-fitting member 43 is moved. A fixing operation of lowering and bringing the moving side member 41 into contact with the fixed side member 44 is performed.

In the case of sequentially performing such positioning operation and fixing operation, first, the moving side member 41 can be brought into contact with the fixed side member 44 in one stopper mechanism 40B to position the moving carriage 24 with respect to the moving path 28. In the positioning operation, even if there is play between the moving side member 41 and the fixed side member 44, the moving side member 41 of the other stopper mechanism 40A is brought into contact with the fixed side member 44 by the fixing operation. The remaining play can be eliminated, and the movable carriage 24 can be fixed to the movement path 28 in this state.
Therefore, in the present embodiment, the play between the moving carriage 24 and the moving path 28 is eliminated by sequentially performing the positioning operation and the fixing operation described above, and the moving carriage 24 on which the stirring device 20 is placed is securely fixed. And vibration during stirring can be reliably suppressed.

In particular, in this embodiment, two pairs of stopper mechanisms 40A and 40B are provided between the moving carriage 24 and the moving path 28, along the moving direction (R direction) of the moving carriage 24, on both sides of the moving carriage 24. First, a positioning operation can be performed simultaneously with two sets of the pair of stopper mechanisms 40B, and then a fixing operation can be performed simultaneously with two sets of the pair of stopper mechanisms 40A.
In this way, by arranging two sets of the pair of stopper mechanisms 40A and 40B on both sides of the moving carriage 24, for example, the moving carriage 24 moving along the moving path 28 is inclined with respect to the moving path 28 (in the vertical direction). Even if there is rotation around the center, the moving carriage 24 can be positioned in a correct posture with respect to the moving path 28 by two positioning operations. Then, by the subsequent fixing operation, the movable carriage 24 can be fixed to the movement path 28 in a correct posture.
